PADLGs varied in scope, target users, and clinical recommendations, both within and across clinical settings. Most provided recommendations for risk stratification, testing, and delabelling methods, with many supporting direct delabelling\/direct challenge in low\u2010risk patients. Substantial variation was observed in risk assessment tools, eligibility criteria, and post\u2010test delabelling strategies. Overall, the quality of PADLGs was low, with only two meeting predefined high\u2010quality criteria. Critical gaps included limited methodological rigour, poor stakeholder involvement, and lack of guidance for real\u2010world implementation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>To support safe and scalable PADL approaches, clearer, more consistent, and methodologically robust guidelines are needed to address the global burden of inappropriate penicillin allergy labels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Systematic Review Registration<\/jats:title>\n                    <jats:p>\n                      The protocol for this review was prospectively registered at Open Science Framework:\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"http:\/\/osf.io\/9fvr7\">osf.io\/9fvr7<\/jats:ext-link>\n                      .\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/cea.70269","type":"journal-article","created":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T21:06:41Z","timestamp":1773004001000},"page":"867-880","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Quality and Consistency of Penicillin Allergy Delabelling Guidelines: A Systematic Review"],"prefix":"10.1111","volume":"56","author":[{"given":"Jessie","family":"He","sequence":"first","affiliation":[{"name":"Pharmacy, School of Health and Clinical Sciences The University of Western Australia  Perth Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Guirguis","sequence":"additional","affiliation":[{"name":"Pharmacy, School of Health and Clinical Sciences The University of Western Australia  Perth Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sankare","family":"Devanandan","sequence":"additional","affiliation":[{"name":"Pharmacy, School of Health and Clinical Sciences The University of Western Australia  Perth Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rani","family":"Scott\u2010Farmer","sequence":"additional","affiliation":[{"name":"National Allergy Centre of Excellence (NACE)  Parkville Australia"},{"name":"Child Health Research Centre The University of Queensland  Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Vale","sequence":"additional","affiliation":[{"name":"National Allergy Council  Sydney Australia"},{"name":"School of Population &amp;
